DETAILED DESCRIPTION

In the following description, for the purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of various exemplary embodiments or implementations of theinvention. As used herein “embodiments” and “implementations” areinterchangeable words that are non-limiting examples of devices ormethods employing one or more of the inventive concepts disclosedherein. It is apparent, however, that various exemplary embodiments maybe practiced without these specific details or with one or moreequivalent arrangements. In other instances, well-known structures anddevices are shown in block diagram form in order to avoid unnecessarilyobscuring various exemplary embodiments. Further, various exemplaryembodiments may be different, but do not have to be exclusive. Forexample, specific shapes, configurations, and characteristics of anexemplary embodiment may be used or implemented in another exemplaryembodiment without departing from the inventive concepts.

Unless otherwise specified, the illustrated exemplary embodiments are tobe understood as providing exemplary features of varying detail of someways in which the inventive concepts may be implemented in practice.Therefore, unless otherwise specified, the features, components,modules, layers, films, panels, regions, and/or aspects, etc.(hereinafter individually or collectively referred to as “elements”), ofthe various embodiments may be otherwise combined, separated,interchanged, and/or rearranged without departing from the inventiveconcepts.

The use of cross-hatching and/or shading in the accompanying drawings isgenerally provided to clarify boundaries between adjacent elements. Assuch, neither the presence nor the absence of cross-hatching or shadingconveys or indicates any preference or requirement for particularmaterials, material properties, dimensions, proportions, commonalitiesbetween illustrated elements, and/or any other characteristic,attribute, property, etc., of the elements, unless specified. Further,in the accompanying drawings, the size and relative sizes of elementsmay be exaggerated for clarity and/or descriptive purposes. When anexemplary embodiment may be implemented differently, a specific processorder may be performed differently from the described order. Forexample, two consecutively described processes may be performedsubstantially at the same time or performed in an order opposite to thedescribed order. Also, like reference numerals denote like elements.

When an element, such as a layer, is referred to as being “on,”“connected to,” or “coupled to” another element or layer, it may bedirectly on, connected to, or coupled to the other element or layer orintervening elements or layers may be present. When, however, an elementor layer is referred to as being “directly on,” “directly connected to,”or “directly coupled to” another element or layer, there are nointervening elements or layers present. To this end, the term“connected” may refer to physical, electrical, and/or fluid connection,with or without intervening elements. Further, the D1-axis, the D2-axis,and the D3-axis are not limited to three axes of a rectangularcoordinate system, such as the x, y, and z-axes, and may be interpretedin a broader sense. For example, the D1-axis, the D2-axis, and theD3-axis may be perpendicular to one another, or may represent differentdirections that are not perpendicular to one another. For the purposesof this disclosure, “at least one of X, Y, and Z” and “at least oneselected from the group consisting of X, Y, and Z” may be construed as Xonly, Y only, Z only, or any combination of two or more of X, Y, and Z,such as, for instance, XYZ, XYY, YZ, and ZZ. As used herein, the term“and/or” includes any and all combinations of one or more of theassociated listed items.

Although the terms “first,” “second,” etc. may be used herein todescribe various types of elements, these elements should not be limitedby these terms. These terms are used to distinguish one element fromanother element. Thus, a first element discussed below could be termed asecond element without departing from the teachings of the disclosure.

Spatially relative terms, such as “beneath,” “below,” “under,” “lower,”“above,” “upper,” “over,” “higher,” “side” (e.g., as in “sidewall”), andthe like, may be used herein for descriptive purposes, and, thereby, todescribe one elements relationship to another element(s) as illustratedin the drawings. Spatially relative terms are intended to encompassdifferent orientations of an apparatus in use, operation, and/ormanufacture in addition to the orientation depicted in the drawings. Forexample, if the apparatus in the drawings is turned over, elementsdescribed as “below” or “beneath” other elements or features would thenbe oriented “above” the other elements or features. Thus, the exemplaryterm “below” can encompass both an orientation of above and below.Furthermore, the apparatus may be otherwise oriented (e.g., rotated 90degrees or at other orientations), and, as such, the spatially relativedescriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particularembodiments and is not intended to be limiting. As used herein, thesingular forms, “a,” “an,” and “the” are intended to include the pluralforms as well, unless the context clearly indicates otherwise. Moreover,the terms “comprises,” “comprising,” “includes,” and/or “including,”when used in this specification, specify the presence of statedfeatures, integers, steps, operations, elements, components, and/orgroups thereof, but do not preclude the presence or addition of one ormore other features, integers, steps, operations, elements, components,and/or groups thereof. It is also noted that, as used herein, the terms“substantially,” “about,” and other similar terms, are used as terms ofapproximation and not as terms of degree, and, as such, are utilized toaccount for inherent deviations in measured, calculated, and/or providedvalues that would be recognized by one of ordinary skill in the art.

Various exemplary embodiments are described herein with reference tosectional and/or exploded illustrations that are schematic illustrationsof idealized exemplary embodiments and/or intermediate structures. Assuch, variations from the shapes of the illustrations as a result, forexample, of manufacturing techniques and/or tolerances, are to beexpected. Thus, exemplary embodiments disclosed herein should notnecessarily be construed as limited to the particular illustrated shapesof regions, but are to include deviations in shapes that result from,for instance, manufacturing. In this manner, regions illustrated in thedrawings may be schematic in nature and the shapes of these regions maynot reflect actual shapes of regions of a device and, as such, are notnecessarily intended to be limiting.

As customary in the field, some exemplary embodiments are described andillustrated in the accompanying drawings in terms of functional blocks,units, and/or modules. Those skilled in the art will appreciate thatthese blocks, units, and/or modules are physically implemented byelectronic (or optical) circuits, such as logic circuits, discretecomponents, microprocessors, hard-wired circuits, memory elements,wiring connections, and the like, which may be formed usingsemiconductor-based fabrication techniques or other manufacturingtechnologies. In the case of the blocks, units, and/or modules beingimplemented by microprocessors or other similar hardware, they may beprogrammed and controlled using software (e.g., microcode) to performvarious functions discussed herein and may optionally be driven byfirmware and/or software. It is also contemplated that each block, unit,and/or module may be implemented by dedicated hardware, or as acombination of dedicated hardware to perform some functions and aprocessor (e.g., one or more programmed microprocessors and associatedcircuitry) to perform other functions. Also, each block, unit, and/ormodule of some exemplary embodiments may be physically separated intotwo or more interacting and discrete blocks, units, and/or moduleswithout departing from the scope of the inventive concepts. Further, theblocks, units, and/or modules of some exemplary embodiments may bephysically combined into more complex blocks, units, and/or moduleswithout departing from the scope of the inventive concepts.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which this disclosure is a part. Terms,such as those defined in commonly used dictionaries, should beinterpreted as having a meaning that is consistent with their meaning inthe context of the relevant art and should not be interpreted in anidealized or overly formal sense, unless expressly so defined herein.

The display device DD according to an exemplaryembodiment of the inventive concepts may be applied to large-sizedelectronic devices such as televisions and monitors and small andmiddle-sized electronic devices such as tablet PC, navigation units forvehicles, game consoles, and smart watches.

As illustrated in FIG. 1, the display surface DD-IS includes an imagearea DD-DA on which an image IM is displayed and a bezel area DD-NDAadjacent to the image area DD-DA. The bezel area DD-NDA may be an areaon which an image is not displayed. FIG. 1 illustrates an icon as anexample of the image IM.

As illustrated in FIG. 1, the image area DD-DA may have a substantiallyrectangular shape. The “substantially rectangular shape” includes notonly a rectangular shape as a mathematical sense but also a rectangularshape in which a vertex is not defined in a vertex area (or a cornerarea) but a boundary of a curve is defined.

The bezel area DD-NDA may surround the image area DD-DA. However,exemplary embodiments of the inventive concepts are not limited thereto.For example, the image area DD-DA and the bezel area DD-NDA may berelatively designed in shape.

FIGS. 2A to 2D are cross-sectional views of the display device accordingto an exemplary embodiment of the inventive concepts. FIGS. 2A to 2Dillustrate cross-sections defined by the second directional axis DR2 andthe third directional axis DR3. FIGS. 2A to 2D are simply illustrated toexplain a lamination relationship of functional members constituting thedisplay device DD.

The display device DD according to an exemplary embodiment of theinventive concepts may include a display panel, an input sensor, ananti-reflector, and a widow. At least portions of the display panel, theinput sensor, the anti-reflector, and the window may be formed through acontinuous process, and at least portions may be coupled to each otherthrough an adhesion member. FIGS. 2A to 2D illustrate an optically clearadhesive (OCA) as an example of the adhesion member. Hereinafter, theadhesion member may include a general adhesive or adhesive agent. In anexemplary embodiment of the inventive concepts, the anti-reflector andthe window may be replaced with different constituents or omitted.

In FIGS. 2A to 2D, a corresponding constituent of the input sensor, theanti-reflector, and the window, which is formed with respect to theother constituent through the continuous process, may be expressed as a“layer”. Also, a constituent of the input sensor, the anti-reflector,and the window, which is coupled to the other constituent through theadhesion member, may be expressed as a “panel”. The “panel” may includea base layer providing a base surface, for example, a synthetic film, acomplex material film, a glass substrate, and the like, but the baselayer may be omitted in the “layer”. That is to say, the units expressedas the “layer” may be disposed on the base surface provided by the otherunit.

Here, the input sensor, the anti-reflector, and the window may be calledan input sensing panel ISP, an anti-reflection panel RPP, and a windowpanel WP or an input sensing layer ISL, an anti-reflection layer RPL,and a window layer WL.

As illustrated in FIG. 2A, the display device DD may include a displaypanel DP, an input sensing layer ISL, an anti-reflection panel RPP, anda window panel WP. The input sensing layer ISL may be directly disposedon the display panel DP. In this specification, that “a constituent B isdirectly disposed on a constituent A” may mean that a separate adhesivelayer/adhesive member is not disposed between the constituents A and B.The constituent B may be formed through the continuous process on thebase surface provided by the constituent A after the constituent A isformed.

The display panel DP and the input sensing layer ISL directly disposedon the display panel DP may be defined as a display module DM. Anoptically clear adhesive (OCA) is disposed between the display module DMand the anti-reflection panel RPP and between the anti-reflection panelRPP and the window panel WP.

The display panel DP generates an image, and the input sensing layer ISLacquires coordinate information of an external input (for example, atouch event). Although not separately shown, the display module DMaccording to an exemplary embodiment of the inventive concepts mayfurther include a protection member disposed on a bottom surface of thedisplay panel DP. The protection member and the display panel DP may becoupled to each other through an adhesion member. The display devices DDof FIGS. 2B to 2D, which will be described below, may also furtherinclude the protection member.

The display panel DP according to an exemplary embodiment of theinventive concepts may be an emission type display panel, but is notlimited thereto. For example, the display panel DP may be an organiclight emitting display panel and a quantum-dot light emitting displaypanel. A light emitting layer of the organic light emitting displaypanel may include an organic light emitting material. A light emittinglayer of the quantum dot light emitting display panel may include aquantum dot, a quantum rod, and the like. Hereinafter, the organic lightemitting display panel will be described as an example of the displaypanel DP.

The anti-reflection panel RPP reduces reflectance of external lightincident from an upper side of the window panel WP. The anti-reflectionpanel RPP according to an exemplary embodiment of the inventive conceptsmay include a retarder and a polarizer. The retarder may be a film typeor liquid crystal coating type retarder and may include a λ/2 retarderand/or a λ/4 retarder. The polarizer may also be a film type or liquidcrystal coating type polarizer. The film type may include anelongation-type synthetic resin, and the liquid crystal coating type mayinclude liquid crystals that are arranged in a predeterminedarrangement. Each of the retarder and the polarizer may further includea protection film. The retarder and polarizer itself or the protectionfilm may be defined as a base layer of the anti-reflection panel RPP.

The anti-reflection panel RPP according to an exemplary embodiment ofthe inventive concepts may include color filters. The color filters mayhave predetermined arrangement. The color filters may be determined inarrangement in consideration of colors of light emitted from pixelsprovided in the display panel DP. The anti-reflection panel RPP mayfurther include a black matrix adjacent to the color filters.

The anti-reflection panel RPP according to an exemplary embodiment ofthe inventive concepts may include a destructive interference structure.For example, the destructive interference structure include firstreflection layer and a second reflection layer, which are disposed onlayers different from each other. First reflected light and secondreflected light, which are respectively reflected from the firstreflection layer and the second reflection layer, may destructivelyinterfere, and thus, the external light may be reduced in reflectance.

The emission areas PXA-R, PXA-B, and PXA-G of the first emission areagroup include cell units CU1 and CU2 arranged in an n×n matrix, where nis a natural number 10 or more.

A 1-th row 1stL, an n-th row n-thL, a 2-th row 2ndL, 1-th column 1stC, a2-th column 2ndC, and an n-th column n-thC are schematicallyillustrated. The cell units include first cell units CU1 and second cellunits CU2.

Each of the first cell units CU1 includes a first emission area PXA-Rand a third emission PXA-G arranged in a diagonal direction DR4 (or afourth direction). Each of the second cell units CU2 includes a secondemission area PXA-B and a third emission PXA-G arranged in a diagonaldirection DR4.

The first cell units CU1 and the second cell units CU2 of the firstemission area group have a first arrangement. In each of the rowsarranged in n×n matrix, the first cell units CU1 and the second cellunits CU2 are alternately disposed. When the 1-th cell unit of theodd-numbered rows is the first cell unit CU1, the 1-th cell unit of theeven-numbered rows may be the second cell unit CU2.

As illustrated in FIG. 7C, the 1-th cell unit of the 1-th row of thefirst emission group may be the first cell unit CU1, and the n-th cellunit of the 1-th row may be the first cell unit CU1. The 1-th cell unitof the last row of the first emission group may be the first cell unitCU1, and the n-th cell unit of the n-th row n-thL may be the first cellunit CU1. As illustrated in FIG. 7C, the 1-th emission area of the 1-themission area row corresponding to the first sensing area S1 may be thefirst emission area PXA-R.

That the first cell units CU1 and the second cell units CU2 of the firstemission group have the first arrangement may be the same as that thefirst openings OP-MR, the second openings OP-MB, and the third openingOP-MG disposed in the first sensing areas S1 have the first arrangement.This is done because the first openings OP-MR, the second openingsOP-MB, and the third opening OP-MG one-to-one correspond to the firstemission area PAX-R, the second emission area PXA-B, and the thirdemission area PXA-G.

Referring to FIG. 7D, the two second connection parts CP2 connect thetwo second sensing parts SP2, which are spaced apart from each other.First to fourth connection areas CNT-A1 to CNT A4 are disposed betweenthe two second connection parts CP2 and the two second sensing partsSP2.

Contact holes CNT-I may be defined in each of the first to fourthconnection areas CNT-A1 to CNT A4. The first connection area CNT-A1 andthe second connection area CNT-A2 may disposed by using the secondemission area PXA-B as a center, and the third connection area CNT-A3and the fourth connection area CNT-A4 may be disposed by using the firstemission area PXA-R as a center.

The second connection part CP2 crosses a mesh line of the first sensingpart SP1. The second connection part CP2 may be replaced with the meshline of the first sensing part SP1 within the crossing area. The meshline of the second connection part CP2 and the mesh line of the firstsensing part SP1 may not overlap each other except for crossing points.The mesh line of the second connection part CP2 and the mesh line of thefirst sensing part SP1 may define openings replaced with the firstopenings OP-MR, the second opening OP-MB, and the third opening OP-MG.

The second rule will be described with reference to FIGS. 7E to 7G. Thesecond sensing area S2 of FIG. 7E has a structure similar to that of thefirst sensing area S1 of FIG. 7B. Referring to FIG. 7F, the emissionareas disposed on the second sensing area S2 of the plurality ofemission areas PXA-R, PXA-B, and PXA-G may be defined as a secondemission area group.

The emission areas PXA-R, PXA-B, and PXA-G of the second emission areagroup include first cell units CU1 and second cell units CU2 arranged inan n×n matrix. The first cell units CU1 and the second cell units CU2 ofthe second emission area group have a second arrangement different fromthe first arrangement described with reference to FIG. 7C.

The second arrangement is different from the first arrangement of FIG.7C in that the first cell units CU1 and the second cell units CU2 areexchanged in position. When the 1-th cell unit of the odd-numbered rowsis the second cell unit CU2, the 1-th cell unit of the even-numberedrows may be the first cell unit CU1.

As illustrated in FIG. 7F, the 1-th cell unit of the 1-th row 1stL ofthe second emission group may be the second cell unit CU2, and the n-thcell unit of the 1-th row 1stL may be the second cell unit CU2. The 1-thcell unit of the n-th row n-thL of the second emission group may be thesecond cell unit CU2, and the n-th cell unit of the n-th row n-thL maybe the second cell unit CU2. As illustrated in FIG. 7F, the 1-themission area of the 1-th emission area row corresponding to the secondsensing area S2 may not be the first emission area PXA-R but be thesecond emission area PXA-B.

That the first cell units CU1 and the second cell units CU2 of thesecond emission group have the second arrangement may be the same meanas that the first openings OP-MR, the second openings OP-MB, and thethird opening OP-MG disposed in the second sensing areas S3 have thesecond arrangement.

Referring to FIG. 7G, the two second connection parts CP2 connect halfof the two second sensing parts SP2 to each other. The crossing area ofthe second sensing area S2 may have a structure similar to the crossingarea of the first sensing area S1.

Referring to FIG. 7G, first to fourth connection areas CNT-A1 to CNT A4are disposed between the two second connection parts CP2 and the twosecond sensing parts SP2. The first connection area CNT-A1 and thesecond connection area CNT-A2 may disposed by using the first emissionarea PXA-R as a center, and the third connection area CNT-A3 and thefourth connection area CNT-A4 may be disposed by using the secondemission area PXA-B as a center.

As illustrated in FIGS. 7C and 7F, the reason in which the first andsecond emission groups adjacent to each other in the same row have theemission arrangements different from each other is because the first andsecond emission groups respectively have the odd-numbered rows and theeven-numbered rows. In addition, this is done because the arrangement ofthe first type emission row PL1, the second type emission area PL2, andthe third type emission row PL3, which are described with reference toFIG. 6E, is repeated.

In an exemplary embodiment of the inventive concepts, although the firstand second emission groups do not have the odd-numbered rows and theeven-numbered rows, the arrangement relationship between the firstemission area PXA-R, the second emission area PXA-B, and the thirdemission area PXA-G, which is described with reference to FIG. 6E, maybe changed to achieve the same result.

Referring to FIGS. 7C and 7F, a boundary between the first sensing partSP1 and the second sensing part SP2 may be defined by disconnectionpoints of the mesh line. The disconnection pints of the first sensingpart SP1 and the second sensing par SP2 of FIG. 7C may define a firstboundary pattern BP1 of FIG. 7H. The disconnection points of the firstsensing part SP1 and the second sensing part SP2 of FIG. 7F may define asecond boundary pattern BP2 of FIG. 7H. The first boundary pattern BP1and the second boundary pattern BP2 may connect the disconnection pointsto each other at the shortest distance.

The first boundary pattern BP1 and the second boundary pattern BP2 haveshapes different from each other. As described above, the openingsOP-MR, OP-MB, and OP-MG or the emission areas PXA-R, PXA-B, and PXA-G ofthe first sensing area S1 may have the first arrangement, and theopenings OP-MR, OP-MB, and OP-MG or the emission areas PXA-R, PXA-B, andPXA-G of the second sensing area S2 may have the second arrangement.

Also, due to the above-described reasons, the mesh line of the firstsensing area S1 has a first shape, and the mesh line of the secondsensing area S2 has a second shape different from the first shape. Sincethe openings OP-MR, OP-MB, and OP-MG are defined by the mesh line ML,the mesh line ML may be needed to be deformed so as to change thearrangement of the openings OP-MR, OP-MB, and OP-MG.

As illustrated in FIG. 7I, the input sensor IS may further include adummy pattern DDP that is insulated from the electrodes IE1-1 to IE1-10of the first electrode group EG1 and the electrodes IE2-1 to IE2-8 ofthe second electrode group EG2. The dummy pattern DDP may be a floatingpattern spaced apart from the sensing electrodes. The dummy pattern DDPmay be disposed on the same layer as the first sensing parts SP1 and thesecond sensing parts SP2. In this embodiment, the dummy pattern DDP maybe formed from the second conductive layer CL2.

The dummy pattern DDP may be disposed at a center of an area defined bya (k, j) sensing area, a (k+1, j) sensing area, a (k, j+1) sensing area,and a (k+1, j+1) sensing area of the sensing areas arranged in the p×qmatrix, which is described with reference to FIG. 7A. Where k is anatural number of p or less, and j is a natural number of q or less. Thedummy pattern DDP may be disposed on the boundary of the four sensingareas adjacent to each other to reduce a parasitic cap between theelectrodes disposed in different rows and different columns.

The emission areas disposed onthe fourth sensing area S4 of the plurality of emission areas PXA-R,PXA-B, and PXA-G may be defined as a fourth emission area group.

The openings OP-MR, OP-MB, and OP-MG defined in the third sensing areasS3 may have a third arrangement different from the first and secondarrangements described with reference to FIGS. 6A to 7I. Since the thirdsensing areas S3 has a surface area less than that of each of the firstsensing area S1 and the second sensing area S2, the third sensing areasS3 may include the small number of openings OP-MR, OP-MB, and OP-MG (seeFIG. 6).

The openings OP-MR, OP-MB, and OP-MG (see FIG. 6E) defined in the fourthsensing areas S4 may have a fourth arrangement different from the firstand second arrangements described with reference to FIGS. 6A to 7I.

Asillustrated in FIG. 7F, since the 1-th cell unit of the 1-th row 1stL ofthe second emission group is the second cell unit CU1, the n-th cellunit of the fourth emission group is the first cell unit CU1. Asdescribed above, the cell units disposed at corresponding positions ofthe third emission group and the fourth emission group are differentfrom each other. That the cell units disposed at the correspondingpositions are different from each other has the same mean as that theopenings OP-MR, OP-MB, and OP-MG defined in corresponding positions aredifferent from each other.

The outer sensing area IS-DA2 may further include fifth sensing areasS5, sixth sensing areas S6, and seventh sensing areas S7. In the fifthsensing areas S5 and the sixth sensing areas S6, the openings OP-MR,OP-MB, and OP-MG have an arrangement different from the first and secondarrangements, like the third and fourth sensing areas S3 and S4. Thefifth sensing areas S5 and the sixth sensing areas S6 may be disposedbelow the first sensing area S1 and the second sensing area S2.

Theemission areas disposed on the fourth sensing area S4 of the pluralityof emission areas PXA-R, PXA-B, and PXA-G may be defined as a fourthemission area group.

The openings OP-MR, OP-MB, and OP-MG defined in the third sensing areasS3 may have the same arrangement as the first arrangement described withreference to FIGS. 6A to 7I. However, a boundary pattern (hereinafter,referred to as a third boundary pattern) of the third sensing areas S3may have a shape different from that of each of the first boundarypattern BP1 and the second boundary pattern BP2 of FIG. 7H. That is tosay, a mesh line of the third sensing area S3 may have a third shapedifferent from each of the first and second shapes.

The openings OP-MR, OP-MB, and OP-MG defined in the fourth sensing areasS4 may have the same arrangement as the second arrangement describedwith reference to FIGS. 6A to 7I. However, a boundary pattern(hereinafter, referred to as a fourth boundary pattern) of the fourthsensing areas S4 may have a shape different from that of each of thefirst boundary pattern BP1 and the second boundary pattern BP2 of FIG.7H. That is to say, a mesh line of the fourth sensing area S4 may have afourth shape different from each of the first and second shapes.
